摘要
The dielectric and phase transitional properties were investigated for Tl2ZnBr4 and Tl2CoBr4, both of which are compounds having the crystal structure of Sr2GeS4-type at room temperature. The differential thermal analysis(DTA) and dielectric measurements revealed that both crystals have the transition at around 18 K accompanied by a lambda-type dielectric constant anomaly and the so-called alpha-beta transition at around 480 K from the Sr2GeS4-type phase to the high temperature beta-K2SO4-type phase.
